Portable type memory device

摘要: A portable type memory device has a lead 10A of ground terminal formed in connector 2 for communicating data, which extends and bends to contact with an area conductive cover 4 where insulating material 3 been removed. When static electricity external noise are applied the device, they can be conducted thus electric current caused by such is not supplied mounting parts or wiring so as prevent latch up ICs 8, deterioration destruction internal elements. In another arrangement two grounding leads provided, one each covers 4.
